Jimi,
It may be the the difference in resistance between the mouthpieces that is affecting things more than the weight. Have you tried using a BERP or buzzing tube to see if it helps? I regularly use a tube myself, and adding a little resistance has made a big difference for several other people I know...making buzzing more helpful. You still need to use plenty of air like Manny says, but the tube can provide the balance needed to keep you from adjusting.

Let me know if you want the dimensions for making your own tube and I'll send them. Hope this helps.
